thanks matt, but I couldn't see any question regarding binding a component,in both link, and also the second link is for 2 version of the Seam I am using 1.1.6 and at the moment I can't upgrade to version 2.

astonishingly, when I press Save button to update changes, at server-side only changes to last text box is being seen and others remained intact and when I substitute another text box say "phone no" with the last one (change their position) again only changes to last text box (phone no) is visible and the others have the same value they already had
